| Abstract: | Based on the electro magneto elastic theory and the theory of the bending vibration of the electric beam,nonlinear vibration equation of current carrying beam in thermal magneto elasticity field is studied.The Electromagnetic force and thermal force on the beam are derived.In addition,according to the Galerkin Method,the corresponding nonlinear vibrations differential equations are derived.Through the numerical calculation,the time history response plots and the phase charts are obtained with different system parameters. |
